7 Measurement and Adjustments
7.1. Adjustment Procedure Flowchart
7.2. Cautions for Adjustment
·
Never unplug the power cord until the power indicator on the projector illuminates red.
·
To maintain and ensure safety, always use the designated components for replacement parts.
·
If removing any clamps, lead wires or connectors, always place them back in their proper locations.
·
Be careful not to damage the lead wires or components when using a soldering iron or similar tool.
7.3. Setting Before Adjustment
·
Set up the projector to obtain the projection distance below.
·
Turn the zoom ring of the projector to obtain the largest size of the picture.
7.4. Convergence Adjustment
Execute this adjustment when replacing the LCD panel (B).
7.4.1. Tools to be used
Service Kit (Part No. TZSH07003): This kit is composed of 3 extension flexible cables and 2 connector extension cables.
Note:
·
Consult your dealer or Authorized Service Center for the service kit.

fixing the panel attachment.
2. Reassemble the projector in the reverse order of disassembling, but leave the upper case and the screws fixing the A-
P.C.Board block as they are removed.
3. Connect the service kit (extension cables).
·
Each flexible cable of LCD Panels (R/G/B) - Connectors (A13/A14/A15) on A-P.C.Board
·
Exhaust fan connector - Connector (A8) on A-P.C.Board
·
Exhaust air thermosensor connector - Connector (A2) on A-P.C.Board
4. Covering with an insulator (cloth or the like) to prevent a short circuit, set the A-P.C.Board block on the main unit.
Note:
·
Handle with care not to apply external force to connecting parts which connect the main unit and A-P.C.Board block.
7.4.3. Adjustment Procedure
Prepare 2 pieces of thick black paper (23 mm × 100 mm) that can be shaded.
·
Cover and shade LCD panels (R) and (G) with the paper.
1. Display the green crosshatch pattern and adjust the lens focus.
2. Display green and blue crosshatch patterns.
3. Adjust focus by shifting the panel adjuster for LCD panel (B) back and forth, then tighten the 2 screws.
4. Adjust the LCD panel (B) position so that the vertical center of blue crosshatch pattern is overlapped with the vertical center of
green crosshatch pattern.
5. Adjust the LCD panel (B) position so that the horizontal center of blue crosshatch pattern is overlapped with the horizontal
center of green crosshatch pattern.
6. Correct the tilt of the blue crosshatch pattern by adjusting the LCD panel (B) position.
7. Display green, red and blue crosshatch patterns and confirm the convergence. If it is necessary, fine adjust the convergence
so that the blue crosshatch pattern is overlapped with green one.
